Computer Instructions or data, anything that can be stored electronically is Software.
Hardware is one that is tangible. The storage devices (Hard disk, CD’s etc.,), mouse, keyboard CPU and display devices (Monitor) are Hardware.
For example: There is a problem in the Software implies –Problem with program or data
